That cross, which once stood on a bend in the road leading to Cooldrinagh, also known as the Long Acre, to the south of the 17th-century Lucan House, has since vanished entirely from the landscape. No surface remains survive above ground today. What makes this particular absence quietly compelling is how completely a once-visible local landmark can dissolve into the ground, leaving only a cartographer's note and a later writer's passing reference to mark that it ever existed.

The 1699 map, held in the National Library of Ireland as MS 39/251/3, was drawn up as part of a set of title deeds relating to the lands of Pettycannon, a name that records their earlier ownership by the Petty Canons and Choristers of St Patrick's Cathedral, Dublin. The map places the cross opposite the entrance to Lucan House, a position that would have made it a conspicuous feature of the approach to one of the area's principal estates. By 1837, Samuel Lewis in his Topographical Dictionary of Ireland was still noting its presence, or at least its remembered presence, opposite that same entrance. Local archaeologist Helen Farrell has since identified a granite cross-base with a small circular-shaped socket in the graveyard to the west of St. Mary's Church, Lucan. A cross-base is essentially the heavy stone footing into which the shaft of a standing cross would have been set; the socket is the hole that once held it upright. This fragment may well be the physical remnant of the cross shown on the 1699 map, though the connection remains tentative.

The graveyard lies to the west of St. Mary's Church in Lucan village, and the cross-base, if you know to look for it, sits within that burial ground. It is an unassuming piece of worked granite, easily overlooked without prior knowledge of what it represents. There is no marker drawing attention to it, and the socket in its surface is modest in scale. The surrounding area retains little obvious trace of the road bend and estate entrance that once gave the original cross its context, though the general topography of the village still follows lines that would have been recognisable to whoever annotated that map more than three centuries ago.
